When I post a screen grab as an attachment, it comes in gif or png (because its graphics). But when Uploading it, it gets converted by the server script to .jpg. The result can look very fuzzy or bad.

Can this be reconfigured so gif's remain gif's? The usual explanation, that that feature does not exist, should not apply, since JPEG conversion, would be the extra future. Just need it to stop modifying all image types.
